Containers

ABSTRACT

A container for two products which must be kept separately from each other, but which should be mixed at the time of use, comprises a body having an open upper end and a lower bottom provided with an upwardly extending partition to determine two separate chambers. A cover closes both chambers in a fluidtight manner and it includes a upwardly directed hollow extension having an inner dividing partition which delimits therein two subspaces each communicating with one of the chambers. At the time of use this extension is cut horizontally below its closed upper end and it thus forms a double discharging spout for the contents of both chambers.

m 3 2 H N I i E i i I 5 5 g h W g i E 1 E 5 '11 i x i s CONTAINERS This invention has for its object a container adapted to contain two products which must be kept separate from each other but which should be used simultaneously.

As an-example of such products reference may be had to sauces for salad. Such sauces are generally formed of a mixture in suitable proportions of oil, vinegar and condiments (salt, pepper, mustard, etc...). Experience demonstrates that the-vinegar with the condiments in the diluted state should be i kept separately of the oil, the mixture being effected at the time of use.

The container according to the invention comprises two coaxial chambers separated from each other by an inner annular-partition, and a cover formed with two concentric ribs having a groove adapted to fit on the upper edge of the container body and of its inner annular partition, the said cover further being formed with an upward hollow extension having an innerdividing partition which delimits therein two subspaces each communicating with one of the said chambers. This extension is adapted to be severed at the time of use of the contents in order to form a combined discharging spout.

In the accompanying drawings:

FIG. 1 is a vertical section of an embodiment of a container according to the invention, the cover being shown spaced from the container body.

FIG. 2 is a fragmental view similar to FIG. I, but with the cover mounted in position on the container body.

FIG. 3 is a small scale vertical section of a modified embodiment.

Referring to FIGS. 1 and 2 the container illustrated comprises a body I having an open upper end and a cover 2 1 adapted to form a fluidtight closure for the open end of body The body 1 of the container is of generally cylindrical shape. It comprises an outer wall I which preferably flares I slightly upwardly asshown, the lower end of this outer wall being closed by a fiat disclike bottom 11 disposed somewhat above the'lower edge of the said wall in order too provide a lower circular supporting rib in a per se known manner. The upper edge of theouter wall of body 1 is formed with an out wardly protruding'bead 12. The bottom 11 supports an inner annular partition 13, coaxial to the outer wall and which extends upwardly within body I so as to define therein two coaxial chambers I4 and of predetennined volumes. It will benoted that the upper edge of partition I3 is substantially situated at the same level as the beaded edge 12 of the outer wall I0 of body 1.

Body 1 is preferably made of an appropriate rigid or semirigid synthetic material, wall I0, bottom II and partition 13 being integral with each other.

The cover or closure member 2 is preferably made of a relatively flexible synthetic material. It comprises a flat annular portion delimited by two circular ribs 21 and 22 of inverted U-shaped section which protrude upwardly above the upper side of portion 20. Each rib 21, 22 thus defines a downwardly opening circular groove 21a, 22a adapted to respectively receive the upper edge of the outer wall 10 of the container body I and of the inner annular partition I3 of same. The groove 2Ia of the outer rib 21 has on its outer wall an inwardly projecting circular tooth 23 of substantially triangular cross section, adapted to resiliently snap under the outer bead 12 of the upper edge of wall 10. Cover 2 further comprises a flat disclike central portion 24 situated at a somewhat lower level than the annular portion 20.

Cover 2 is further formed with a tubular boss 25 forming an upwardly directed hollow cylindrical extension disposed at an eccentric position on the upper side of cover 2 in such manner as to overlap a portion of the inner rib 22. The upper end of boss 25 is closed by two oblique walls 26 and 27 which form an upwardly opening Vshaped valley, as shown, the bottom of this valley being in plan view in the form of an arc of a circle disposed just above the portion of rib 22 situated within boss 25. This bottom is connected with rib 21 and with the cylindrical wall of boss 25 by an arcuate partition 28 which may be considered as a solid upward extension of rib 22. The downwardly opening groove of the latter extends in the por tion corresponding to partition 28, as indicated at 29.

It will be understood that the cover 2 thus constructed may be forced downwardly on the container body I to close the latter in a perfectly fluidtight manner, with the tooth 23 snapping under the bead I2 of wall 10 to retain the said cover in position. Chambers 14 and I5 are thus separated from each other, each communicating with one of the subspaces determined by partition 28 within boss 25. At the time of use the user merely severs boss 25 substantially along the horizontal plane XY of FIG. 2 in such manner as to uncover the two inner subspaces situated on each side of partition 28. The contents of both chambers I4 and I5 are thus mixed and discharged simultaneously through boss 25 which thus forms a discharging spout.

In the modification illustrated in FIG. 3 the cover adapted to be associated with the container body I is formed of two coaxialy conical walls I2I and 122 having a common upper apex. The outer conical wall 121 has a lower horizontal annular flange portion I23 formed with an outer depending rim adapted to fit around the beaded upper edge of the outer wall of the container body I, while the lower edge of the inner conical wall I22 comprises a downwardly opening U-shaped circular rib 124 which receives in a fluidtight manner the upper edge of the annular partition of body 1. The conical walls I22 and 123 are further connected with each other by a number of radial stays 125. Here again when the cover 120 is mounted on the container body 1, the coaxial chambers 14 and 15 are wholly separated from each other. The upper end of the cover may be severed horizontally in such manner as to determine an an double opening through which the contents of both chambers may be poured in the mixed state.
